To aZZ whom it may concern.-

Be it known that LiLAWRENOE SACK, a' citizen of the United States, and aresident of Farwell, in the county of Howard, State of Nebraska,haveinvented certain new and useful Improvements in Combination Grain-Drills, of which the following is a specification.

My invention, which relates tograin-drills, has for its object theproduction of a machine of this character which is adapted to be usedalternately as a drill, as a cultivator for listed corn, and as apulverizer.

The nature of the invention will be readily comprehended, referencebeing had to the following description of the construction and operationand resultant advantages and to the accompanying drawings, in .which theinvention is illustrated in its preferred form, it being understood thatvarious changes and modifications may be madetherein without departingfrom the spirit of the invention as defined by the claims.

In the drawings,Figure 1 is a plan view of a machine embodying myinvention. Fig. 2 is a side elevation. Fig. 3 is a detail perspectiveview of a lister attachment.

Referring to the drawings by letters, A denotes the frame of themachine, consisting of a front bar A and rearwardly-extending side barsA A the latter being connected together toward their ends by a cross-barA Centrally and longitudinally of the frame is a reachbar A, on the rearend of which is so pported the operators seat.

E is a shaft extending transversely of the frame and having hearings inthe rear ends of the side bars and reach-bar. The shaft ends, whichextend beyond the side bars, are each equipped with a head f, throughwhich extends a leg g, said legs being carried by the axle-stubs E, onwhich are journaled the rear wheelsE The legs g are slidable in theheads f, whereby to closely adj ust the height of the rear end of theframe for regulating the depth of the drill, the adjustment beingmaintained by tightening a set-nut f.

Further adjustment of the frame is also effected by movement of a handlever cl, clamped at its inner end to the shaft E, whereby movement ofthe lever swings the wheels E longitudinally of the frame, the diiferentbolt are coincident.

steps of adjustment being maintained by a hand-released spring-pressedlocking device on the lever engaging a toothed segment (1, carried bythe cross-bar A Extended move- .ment of the lever, as shown in Figs. 1and 2, throws the machine out of gear by elevating the drill-shoes abovethe surface of the ground.

The reach-bar A at its forward end is formed to provide a substantiallyrectangular vertically-disposed frame having guideopenings for aslidable king-post X, to the lower end of which the truck E .of thefront wheels E E is pivoted. The front axle-tree c is provided at itsends with apertured heads 0, which slidably receive legs F on the frontaxle-stubs. The forward portion of the frame A is therefore verticallyadj nstable in a manner similar to the manner of adjustment of therearward portion of the frame, the adjustment being maintained byset-nuts, as shown. Secured to the king-post above and below its pivotalconnection with the truck 11 are arms 13 B, to the joined ends of whichis hinged a brace-bar B, having at its outer end a loop B which isslidable along the reach-bar A The forward portion of the frame A isvertically movable to throw the machine into and out of gear, and whenin elevated position the bar B serves to brace the extended king-postand relieve it from strain, the loop B in the stated position of theparts shouldering against a projection B on the reach-bar.

The forward portion of the frame A is raised and lowered relatively tothe truck by a lever V, pivoted to a bracket secured in the frame of thereach-bar and provided at its end with a toothed segment WV, whichengages teeth on the kingpost vX. The free end of the lever is withinconvenient reach of the operator, and by raising the lever the forwardend of the frame A is elevated, whereas by depressing the'lever thisframe portion is lowered to throw the machine into gear. The frame islocked in elevated position by a spring-pressed bolt Q, which enters arecess in the king-post when the recess and The king-post is releasedand the frame allowed to fall by the withdrawal of the bolt against theaction of its spring, this being accomplished by pressing downwardly ona foot-lever Q, which is connected with the bolt by a rod Q To throw themachine into or out of gear, the frame is first unlocked by depressingthe foot-lever Q, after which the levers d and V are swung in thedirections which will effect the raising or lowering of the frame,dependent upon which is desired. The depth of entry of the drills isregulated, as before stated, by means of the adjustable connection ofthe frame with the forward and rear trucks, and, if desired, adjustmentof the rear portion of the machine may be accomplished through themedium of the lever 61 and segment 01.

The draft-hound his connected rigidly with the axle-tree 0; but thetongue D is pivotally connected with the axle-tree, whereby the tongueis free from all weight of the machine, and the necks of the horses arerelieved of this weight, the tongue serving merely to guide the machine.

The drills are each composed of two tube sections ll, joined by flexibletubing n and a shoe p. The lower sections are supported to be adjustedlaterally to regulate the distance between rows, each section carrying asleeve M, which is slidable on a shaft is, the position of the drillbeing maintained by a setnut ct, which is inserted into one of a numberof threaded holes M3 in the shaft through a slot a in the sleeve.Preferably three rows of drills are employed mounted in staggeredrelation to each other on three shafts la la k but arranged to permitthe machine to readily pass weeds, stalks, and rubbish without danger ofclogging the drills. It will be understood that the drills are readilyadjustable laterally to provide for increased or decreased distancesbetween rows, the shafts being provided with properly-spaced holes a forthe purpose. The lower drill-sections Z are braced by rods g, which aresecured at one end to the frame and at the other end by wooden pins 6with the drill-section. Ifa drill meets an obstruction which wouldotherwise cause injury thereto in passing, the pin t will break andallow the drill-section to move rearwardly, the slot M permitting suchmovement.

S S denote press wheels or rollers mounted in pairs on the end of an armS, pivoted by means of a sleeve 8 to the shaft 70. Pivoted to the arm isa rod 3, which is guided in an opening in the frame-bar A On this rod iscoiled a spring 8 which operates to press the wheels downwardly. Thewheels are adjusted along the shaft to coincide with the adjustment ofthe drills, and the supporting rear wheels E are provided with long andshort hub projections, whereby each wheel may be reversed in position onthe axle-stub to aline with the outer drills. 'The hopper-box Z isequipped with any suitable feed device operated by sprocket means,including a gear M on the feed-shaft and a pinion L on one wheel E Thegear and pinion have each long and short hub projections, whereby theymay be reversed to preserve alinement when "depth of cut of the disks.

the wheel E is reversed. The shoes 0 may be provided with suitable meansfor scattering the grain at its discharges.

The machine may be converted into a cultivator by removing thehopper-box and pressrollers and by disconnecting the third and fourthdrills at each side of the center drill on shaft it. It will beunderstood that the center drill and center press wheel or roller areimmovablealong the shaft.

The lister corn attachment (shown in Fig. 3 and in dotted lines in Figs.1 and 2) consists of a shoe N, at the rear end of which are mounteddisks N N, the shoe carrying a socketed part n, in the ends of which areadj ustably inserted crank-axles n, which when turned and held by aset-nut n regulates the At the forward end of the shoe is an arm 71 andn is a rod adjustable as to length and pivoted at its lower end to theinner end of the arm n. A spring n connects the arm and rod to press thefree end of the shoe and the disks into the ground. The rod in practiceis inserted in a sleeve 2, fastened on the frame-bar A, and the rear endof the shoe is connected by chains n to the frame at y. It will beunderstood that the disks are adjusted to follow the trenches on listedcorn and are caused to enter the ground by the action of the spring 02When the attachments are in place, the machine is converted into atwo-row corncultivator, the disks operating to clean the sides of thetrenches and the shoe-runners serving to cultivate the ground betweenthe rows.

With the hopper-box and rollers detachedthe machine may be efiectivelyemployed to pulverize stubble-ground.
